this research was conducted to investigate the physico-mechanical characteris-tics of the ethylcellulose-based coating membranes plasticized with different weight percents of dibutyl sebacate. in this experiment, free thin polymer sheetings of the sample formulations, by incorporating incremental weight percents of the plasticizer, were prepared employing a revised casting method of delayed sol...

In the study, basic material for making bioplastics was corn starch with addition of kaolin, microcrystalline cellulose, and chitosan as filler variations, well glycerol a plasticizer. The method used blending method. characterization included absorption test water resistance, biodegradation test, tensile elongation strength functional group analysis using FTIR. Among fillers, best bioplastic c...

Abstract A new oleic acid derivative plasticizer, epoxidized trimethylolpropane trioleate (EPO), has been synthesized and its application in PVC formulations compared with di(2-ethylhexyl) 1,2-cyclohexanoate (DOCH/DEHCH), a commercial phthalate-free plasticizer of petrochemical origin. EPO their blends DOCH were added to resin (50 PHR) the plasticized characterized by thermal mechanical measure...

Abstract The paper presents a study on the effects of thermal aging low-voltage cable. Cable samples with length 50 cm were subjected to cycling from +140 °C −20 in climate chamber controlled temperature. This treatment compares short-term failure or emergency overload some cables under real operating conditions at low temperatures. effect temperature cycle is investigated through electrical me...

Epoxidized vegetable oils are the product of vegetable oil epoxidation reactions. Since the epoxidized vegetable oil is a nonpoisonous plasticizer, it has been wildly used in the plastic packaging of food and medicine. Among the various epoxidized vegetable oils, the application of epoxidized soybean oil is broader than others. Nowadays, it’s the third largest category of plasticizers. However,...

Biodegradable active packaging films based on a cellulose acetate and poly(caprolactone diol) blend with incorporated lemongrass oil were developed. Films prepared using novel bio-based plasticizer, glycerol tritartarate, synthesized the principles of green chemistry. The influence as well essential amount, structural, surface, mechanical, thermal properties was investigated. plasticizer shown ...

In studies conducted to determine the workability of concrete, the bagasse ash and rice husk ash were added as a partial replacement for cement. Trial mixes with the varying water cement ratio, replacement percentage, quantity of super plasticizer and viscosity modifying agent, were prepared and tested. The results were used as the basis for defining three optimum cement replacement mix proport...
